  DESCRIPTION OF EMBODIMENTS Embodiments of a notification system and a program according to the present invention will be described below with reference to the drawings.

<First Embodiment>
FIG. 1 is a diagram illustrating an example of a functional configuration of the notification system 1. The notification system 1 includes a vehicle system 10 and a terminal device 50. The vehicle system 10 and the terminal device 50 communicate using a near field communication standard such as Bluetooth (registered trademark). The vehicle system 10 and the terminal device 50 can communicate by performing authentication (so-called pairing), for example.

[Vehicle system]
The vehicle system 10 is a system mounted on a vehicle. The vehicle is, for example, a vehicle such as a two-wheel, three-wheel, or four-wheel vehicle, and a drive source thereof is an internal combustion engine such as a diesel engine or a gasoline engine, an electric motor, or a combination thereof.

  The vehicle system 10 includes, for example, a camera 12, an acceleration sensor 14, an accelerator pedal opening sensor 16, an operation detection unit 18, a direction indicator 20, a communication device 22, and a vehicle side control unit 30. These devices, devices, control units, and the like are connected to each other by a multiple communication line such as a CAN (Controller Area Network) communication line, a serial communication line, a wireless communication network, or the like. The vehicle system 10 may include an ECU (Electronic Control Unit) that controls each part of the vehicle, in addition to the above functional configuration. The configuration illustrated in FIG. 1 is merely an example, and a part of the configuration may be omitted, or another configuration may be added.

  The camera 12 is a digital camera using a solid-state image sensor such as a CCD (Charge Coupled Device) or a CMOS (Complementary Metal Oxide Semiconductor). One or a plurality of cameras 12 are attached to any part of a vehicle (hereinafter referred to as own vehicle M) on which the vehicle system 10 is mounted. When imaging the front, the camera 12 is attached to the upper part of the front windshield, the rear surface of the rearview mirror, or the like. For example, the camera 12 periodically and repeatedly images the periphery of the host vehicle M. The camera 12 may be a stereo camera.

  In addition to the camera that captures the front, a camera that captures the rear or the lateral direction may be attached to the host vehicle M. Furthermore, in addition to the camera, the host vehicle M may be equipped with a radar device, LIDAR (Light Detection and Ranging), and an object recognition device. The radar device radiates a radio wave such as a millimeter wave around the host vehicle M and detects a radio wave (reflected wave) reflected by the object to detect at least the position (distance and direction) of the object. The LIDAR irradiates light around the host vehicle M, measures scattered light, and detects the distance to the target based on the time from light emission to light reception. The object recognition device recognizes the position, type, speed, and the like of the object by performing sensor fusion processing on detection results of some or all of the camera 12, the radar device, and the LIDAR.

  The acceleration sensor 14 is, for example, an acceleration sensor that detects the acceleration of the host vehicle M. The acceleration sensor 14 is a two-axis or three-axis acceleration sensor, a three-axis gyro sensor, or the like. The vehicle system 10 includes, for example, a vehicle speed sensor that detects a speed, a yaw rate sensor that detects an angular velocity around a vertical axis, an azimuth sensor that detects the direction of the host vehicle M, and the like in addition to the acceleration sensor 14.

  The accelerator pedal opening sensor 16 detects the opening of the accelerator pedal operated by the occupant and outputs the detection result to the vehicle-side control unit 30.

  The operation detection unit 18 detects an operation on the direction indicator 20. For example, the operation detection unit 18 detects whether the direction indicator 20 is blinking (on state) or not blinking (off state), and the detection result is transmitted to the vehicle-side control unit 30. Output to. The direction indicator 20 starts blinking when the driver operates a predetermined operation unit, and stops blinking when an operation to return to a state before operating the predetermined operation unit is performed.

  The communication device 22 communicates with the terminal device 50 using, for example, Bluetooth. The communication device 22 communicates with other vehicles existing around the host vehicle M using, for example, a cellular network, a Wi-Fi network, Bluetooth, DSRC (Dedicated Short Range Communication), or a wireless base station. You may communicate with various server apparatuses via.

  For example, the vehicle-side control unit 30 includes a data acquisition unit 32, a gradient acquisition unit 34, an image analysis unit 36, an object recognition unit 38, a lane recognition unit 40, an information processing unit 42, and a data transmission unit 44. Is provided.

  The data acquisition unit 32 acquires an image captured by the camera 12, an acceleration sensor detection result, an accelerator pedal opening sensor 16 detection result, and an operation detection unit 18 detection result.

  For example, the gradient acquisition unit 34 acquires information capable of recognizing that the host vehicle M is traveling on a downhill road. For example, the gradient acquisition unit 34 derives and acquires the gradient of the road on which the host vehicle M is placed. For example, the gradient acquisition unit 34 is obtained by subtracting the acceleration in the front-rear direction (advance or front-rear axis of the vehicle) obtained by differentiating the vehicle speed detected by the vehicle speed sensor from the acceleration output from the acceleration sensor 14. The slope of the road surface is derived based on the acceleration in the stationary state. And the gradient acquisition part 34 recognizes whether the own vehicle M is drive | working the downhill road more than predetermined degree based on the derived | indicated road surface gradient. The front-rear axial direction of the vehicle is the front-rear direction in a state where the steer wheel of the vehicle is controlled to be neutral. In addition, the gradient acquisition unit 34 may derive the vertical acceleration of the host vehicle M based on the acceleration in a stationary state.

  Further, the gradient acquisition unit 34 specifies the position information of the host vehicle M by a GNSS (Global Navigation Satellite System) receiver, and based on the specified position information and map information including road gradient information, the host vehicle You may recognize that M is traveling downhill. In this case, the vehicle system 1 includes, for example, a GNSS receiver (not shown) and a storage unit in which map information including road gradient information is stored.

  The image analysis unit 36 analyzes the image captured by the camera 12.

  Based on the analysis result of the image analysis unit 36, the object recognition unit 38 detects an object (for example, a preceding vehicle that travels in front of the host vehicle M) and the position of the object that exist around the host vehicle M. For example, the position of the object is recognized as a position on an absolute coordinate with the representative point (the center of gravity, the center of the drive shaft, etc.) of the host vehicle M as the origin. Further, the position of the object may be represented by a representative point such as the center of gravity or corner of the object, or may be represented by a represented area.

  The lane recognition unit 40 recognizes a traveling lane in which the host vehicle M travels or an adjacent lane adjacent to the traveling lane based on the analysis result of the image analysis unit 36.

  Based on the recognition result of the object recognition unit 38 or the recognition result of the lane recognition unit 40, the information processing unit 42 determines the position of the host vehicle M with respect to the traveling lane, the position of the object in the traveling lane, the position of the object with respect to the adjacent lane, Recognize the state of an object. The position of the object is, for example, the position of the object with respect to the lane recognized by the lane recognition unit 40. The state of the object is the speed, acceleration, jerk, etc. of the object. Furthermore, the information processing unit 42 derives the distance (the distance in the traveling direction or the lateral direction) between the object and the host vehicle M based on the recognition result of the object recognition unit 38.

  The data transmission unit 44 transmits the processing result of the vehicle-side control unit 30 to the terminal device 50 using the communication device 22. FIG. 2 is a diagram illustrating an example of the content of data transmitted to the terminal device 50 by the data transmission unit 44. The information transmitted from the vehicle system 10 by the terminal device 50 includes, for example, the position of the object, the position of the traveling lane, the position of the adjacent lane, the speed of the host vehicle M or the object, the acceleration of the host vehicle M or the object, the host vehicle M, for example. Including the slope of the road where the vehicle exists, the acceleration in the front-rear (traveling) direction of the host vehicle M, the acceleration in the vertical direction of the host vehicle M, and the like. Information transmitted from the vehicle system 10 to the terminal device 50 includes, for example, the distance between the host vehicle M and the object (the distance in the traveling direction or the lateral direction), the road marking line between the host vehicle M or the object and the traveling lane, and the like. , The distance between the host vehicle M or the object and the road marking line of the adjacent lane.

[Terminal device]
The terminal device 50 is a terminal device that can be carried by an occupant such as a smartphone or a tablet terminal. The terminal device 50 includes, for example, a communication unit 52, a terminal-side control unit 60, a storage unit 80, a touch panel 92, and an audio output unit 94. The storage unit 80 is realized by, for example, a ROM (Read Only Memory), a flash memory, an SD card, a RAM (Random Access Memory), a register, and the like. In the storage unit 80, for example, a driving evaluation application 82, acquired data 84, and evaluation information 86 are stored.

  The driving evaluation application 82 is an application program provided by a server under the control of an automobile manufacturer and downloaded to the terminal device 50, for example. The driving evaluation application 82 is an application program for evaluating the driving of the driver, and increases the evaluation as the degree to which the host vehicle M follows the preceding vehicle increases. The high degree of following and traveling means that the vehicle is following the preceding vehicle while maintaining a predetermined inter-vehicle distance. The greater the difference between the predetermined inter-vehicle distance and the actual inter-vehicle distance, the lower the degree of follow-up traveling. The predetermined inter-vehicle distance is the inter-vehicle distance from the preceding vehicle set for each speed of the host vehicle M. Since the driving is evaluated by the processing of the driving evaluation application 82, the driver can objectively know his driving. Further, since output information such as driving advice is output by the voice output unit 94 or the like, the driver can receive coaching. The driving evaluation application 82 can also be used when a user other than the driver gives guidance to the driver.

  In addition, the driving evaluation application 82 may lower the driving evaluation when the acceleration of the host vehicle M is equal to or greater than a predetermined value. Furthermore, when the acceleration of the host vehicle M exceeds a predetermined value, the driving evaluation application 82 outputs information on the fact that the acceleration of the host vehicle M has exceeded a predetermined value for driving (touch panel 92, voice output unit 94). ).

  However, driving in a predetermined traffic situation is not subject to evaluation. The predetermined traffic situation is a traffic situation in which it is appropriate to drive the host vehicle M so as to accelerate, or a traffic situation in which acceleration is not caused by a driver's operation. For example, there are traffic situations where highways (or ordinary roads) merge from a merging lane to a driving lane, and traffic situations where a lane is running. The contents of the acquired data 84 and the evaluation information 86 will be described later.

  The communication unit 52 communicates with the vehicle system 10 using, for example, Bluetooth. Further, the communication device 22 may communicate with various server devices via a radio base station using, for example, a cellular network, a Wi-Fi network, Bluetooth, DSRC, or the like.

  The terminal-side control unit 60 is realized by the driving evaluation application 82 being executed by a processor such as a CPU (Central Processing Unit) of the terminal device 50. The terminal-side control unit 60 includes, for example, an acquisition unit 62, a control unit 64, and an evaluation unit 66.

  The acquisition unit 62 stores the information transmitted by the vehicle system 10 in the storage unit 80 as acquisition data 84 (see FIG. 2 described above).

  When the acceleration is equal to or greater than a predetermined value (first predetermined value), the control unit 64 causes the output unit to output a notification that prompts the user to suppress acceleration of the host vehicle M. The acceleration is, for example, acceleration in the front-rear direction of the host vehicle M (acceleration in the vehicle body axis direction of the host vehicle M).

  Even if the acceleration is equal to or greater than a predetermined value, the control unit 64 does not notify in the following cases (1) to (4). (1) is a case where the direction indicator 20 of the host vehicle M is operated. (2) is a case where the host vehicle M is traveling on a downhill road. (3) is a case where the opening degree of the accelerator pedal is smaller than a predetermined value (second predetermined value). (4) is a case where the acceleration in the vertical direction of the host vehicle M is smaller than a predetermined value (third predetermined value).

  The evaluation unit 66 increases the evaluation as the degree of traveling of the host vehicle M following the preceding vehicle increases. The evaluation unit 66 causes the output unit to output an evaluation result (score) after the evaluation in the predetermined section is completed. The evaluation unit 66 stores the processing result as evaluation information 86 in the storage unit 80.

[flowchart]
FIG. 3 is a flowchart showing a flow of processing executed mainly by the control unit 64. In this process, it is assumed that the acquisition unit 62 acquires information about the host vehicle M from the vehicle system 1 at predetermined time intervals.

  First, the control unit 64 determines whether or not the acceleration in the front-rear (front-rear axis) direction of the vehicle body is greater than or equal to a predetermined value Thx (for example, 0.2 G) (step S100). When the longitudinal acceleration of the vehicle body is greater than or equal to the predetermined value Thx, the control unit 64 determines whether or not the direction indicator 20 is in an off state (step S102).

  When the direction indicator 20 is in the off state, the control unit 64 determines whether the vertical acceleration of the vehicle body is equal to or greater than a predetermined value Thz (for example, 1.0 G or a value exceeding 1.0 G). Is determined (step S104). The predetermined value Thz is an example of a “third predetermined value”.

  When the vertical acceleration of the vehicle body is equal to or greater than the predetermined value Thz, the control unit 64 determines whether or not the opening degree of the accelerator pedal is equal to or greater than the predetermined value APth (step S106). The predetermined value APth is an example of a “second predetermined value”.

  When the accelerator opening is equal to or greater than the predetermined value APth, the control unit 64 causes the output unit to perform notification (step S108). When a part of the processes from Step S100 to Step S106 is negative, the control unit 64 does not notify the output unit. Thereby, the process of one routine of this flowchart is completed.

  Note that some of the processes in the flowchart of FIG. 3 described above may be omitted. For example, the process of step S102 may be omitted. For example, one or both of the processes in step S104 or step S106 may be omitted.

  Further, the order of the processing in the flowchart of FIG. 3 described above may be changed. For example, the processing order of step S104 and step S106 may be switched. Moreover, the process of step S102 may be performed after the process of step S104 or step S106.

  By the above-described processing, it is possible to perform notification that matches the actual traffic situation, and it is possible to suppress notification that occurs due to acceleration that does not depend on the driver's operation.

[Scene 1]
FIG. 4 is a diagram illustrating an example of a scene that the control unit 64 causes the output unit to notify. In the scene 1, it is assumed that the user holding the terminal device 50 is driving the host vehicle M on which the vehicle system 10 is mounted. Moreover, in the scene 1, the driving evaluation application 82 is executed, and the driver can receive the evaluation by the driving evaluation application 82 and can receive the coaching.

  In FIG. 4A, the host vehicle M and the preceding vehicle m are stopped by a signal. As shown in FIG. 4B, the signal indicates advancing, the preceding vehicle m starts, and the host vehicle M is about to start following the preceding vehicle m.

  In this case, as shown in FIG. 4C, the driver of the host vehicle M steps on the accelerator to accelerate the host vehicle M in order to follow the preceding vehicle m, but the start timing is delayed. There may be an inter-vehicle distance between the host vehicle M and the preceding vehicle m depending on the degree of travel of the vehicle m and the tracking of the host vehicle M.

  However, it may not be appropriate to cause the host vehicle M to execute acceleration of a predetermined degree or more, such as worsening fuel consumption and power consumption. Therefore, as shown in FIG. 5, the control unit 64 outputs output information indicating that the acceleration is greater than a predetermined degree (for example, “acceleration greater than a predetermined value”). As a result, the driver can recognize that the acceleration is greater than a predetermined degree, and can perform an operation according to the situation on the spot. Further, it is possible to perform more preferable driving coaching with the output content output from the output unit of the terminal device 50.

  In addition, when acceleration more than a predetermined degree is performed, the evaluation part 66 may reduce the evaluation with respect to a driving | operation. In this case, the information on the accelerator opening is not simply output, but the allowance of whether or not it is greater than or equal to a predetermined degree is provided. Therefore, acceleration is not evaluated uniformly, and acceleration below the predetermined degree is evaluated low. You do n’t have to.

  The output information may be information that prompts the user to suppress acceleration of the vehicle. The information prompting to suppress acceleration may be various expressions such as “Let's suppress” and “It is more than a predetermined degree”. For example, when “It is a predetermined degree or more” is output, the user can recognize the degree of operation of the user based on the output information and can recognize that the suppression is promoted. The information that prompts to suppress acceleration includes information that recommends that the operation be suppressed within a threshold value. For example, the output of information recommending that this operation be suppressed within a threshold includes the output of information indicating that the operation of the vehicle has exceeded the threshold, and the driver can suppress the output in any output. Recognize that you are prompted. In addition, the notification may be any or combination of voice, signal sound, member vibration, lamp lighting, screen display, etc., and may be letters, numbers, symbols, pictures, photos, videos, If it is a change in tone color or display, it may be a change in shape, color, brightness, movement, or the like.

  As described above, by the processing of the driving evaluation application 82, the driver can objectively know his / her driving and can receive coaching based on the output information of the system. It can also be used when a user other than the driver gives guidance to the driver.

  As described above with reference to FIG. 5, notification is performed when acceleration of a predetermined level or more is performed, but depending on the traffic situation, it may be appropriate to perform acceleration of a predetermined level or more. In such a case (for example, in the following scene 2 and scene 3), the control unit 64 does not perform notification.

[Scene 2]
FIG. 6 is a diagram illustrating a scene in which the host vehicle M is controlling the turn indicator 20 to be on during acceleration. As shown in FIG. 6, it is assumed that the host vehicle M and the preceding vehicle m are traveling in the merge lane, and the other vehicle m1 is traveling in the travel lane L2 adjacent to the merge lane L1. Moreover, it is drive | working in order of the front vehicle m, the own vehicle M, and the other vehicle m1 regarding the front-back direction. Consider a case where the driver determines that it is appropriate to join the traveling lane L2 so as to travel in front of the other vehicle m1 in the traveling lane L2. In this case, the driver turns on the direction indicator 20, accelerates at a predetermined degree or more, and merges from the merge lane L1 to the travel lane L2.

  As described above, when the direction indicator 20 is controlled to be in an ON state for merging and the host vehicle M accelerates, the control unit 64 does not notify. By performing such processing, notification that is not appropriate in the actual traffic situation is suppressed.

[Scene 3]
FIG. 7 is a diagram illustrating a scene in which the host vehicle M is traveling on the downhill road R. Description will be made assuming that the front-rear direction (front-rear axis direction) of the vehicle is the X direction and the vertical direction of the vehicle is the Z direction. When traveling on the downhill road R, the host vehicle M has an acceleration αg due to its own weight. The acceleration αg is decomposed into an acceleration αgx in the X direction and an acceleration αgz in the Z direction. The acceleration αgz is, for example, information derived by the vehicle-side control unit 30 based on the detection result of the acceleration sensor 14 and the like. Consider a case where the acceleration αx in the X direction is equal to or greater than a predetermined value Thx. When the acceleration αx is equal to or greater than the predetermined value Thx, the acceleration αx may be caused not only by the driver's operation but also by the influence of the gradient of the downhill road R, that is, the acceleration αg. The acceleration αx is obtained by the following equation (1), for example. “Αh” is an acceleration caused by a driver's operation.
αx = αh + αgx

  Even if the acceleration αx in the X direction is equal to or greater than the predetermined value Thx, the control unit 54 determines that the acceleration αgz in the Z direction is less than the predetermined value Thz and the accelerator opening AP is less than the predetermined value APth. It is determined that the acceleration αx is not less than the predetermined value Thx based on the slope of the downhill road R, not the driver's operation, and no notification is given.

  As described above, when the acceleration αx in the longitudinal direction of the vehicle body is greater than or equal to the predetermined value Thx due to the influence of the downhill road R, the control unit 64 does not notify. By performing such processing, notification suitable for traffic conditions is performed.

  Note that the method for determining whether or not the acceleration equal to or greater than the predetermined value Thx is generated based on the slope of the downhill road R instead of the operation of the driver is not limited to the above-described embodiment. For example, based on the map information in which the relationship between the output of the engine (or motor), which is the power source that drives the vehicle, and the acceleration is associated, the acceleration of the predetermined slope Thx or more is generated by the gradient of the downhill road R. It may be determined whether or not. For example, when an acceleration equal to or greater than a predetermined value Thx is generated even though the engine output is zero, it is determined that the acceleration is generated due to the gradient.

  Moreover, although the terminal side control part 60 demonstrated as what was implement | achieved when the driving evaluation application 82 was performed in embodiment mentioned above, it is not restricted to this. For example, some of the functional units of the terminal-side control unit 60 may be realized by a hardware processor such as a CPU (Central Processing Unit) executing a program (software). In addition, some or all of these components include hardware (circuits) such as LSI (Large Scale Integration), ASIC (Application Specific Integrated Circuit), FPGA (Field-Programmable Gate Array), and GPU (Graphics Processing Unit). Part (including circuit)), or may be realized by cooperation of software and hardware.

  In addition, some or all of the devices and functional units included in the terminal device 50 may be included in the vehicle system 10, and conversely, some or all of the devices and functional units included in the vehicle system 10. May be included in the terminal device 50 as shown in FIG.

  FIG. 8 is a diagram illustrating an example of a functional configuration of the terminal device 50A. The terminal device 50A includes, for example, a camera 12A and an acceleration sensor 14A in addition to the functional configuration of the terminal device 50. The camera 12 </ b> A has a function equivalent to that of the camera 12. The acceleration sensor 14A derives acceleration.

  The terminal device 50A includes a terminal-side control unit 60A instead of the terminal-side control unit 60. In addition to the functional configuration of the terminal-side control unit 60, the terminal-side control unit 60A includes a data acquisition unit 32A, a gradient acquisition unit 34A, an image analysis unit 36A, an object recognition unit 38A, a lane recognition unit 40A, and an information processing unit 42A. And a data transmission unit 44A. The data acquisition unit 32A, the gradient acquisition unit 34A, the image analysis unit 36A, the object recognition unit 38A, the lane recognition unit 40A, the information processing unit 42A, and the data transmission unit 44A are respectively a data acquisition unit 32 and a gradient acquisition unit. 34, the image analysis unit 36, the object recognition unit 38, the lane recognition unit 40, the information processing unit 42, and the data transmission unit 44.

  The terminal device 50A includes a storage unit 80A instead of the storage unit 80. Instead of the driving evaluation application 82, the driving evaluation application 82A is stored in the storage unit 80A. The terminal-side control unit 60A is realized by the driving evaluation application 82A being executed by a processor such as a CPU of the terminal device 50. When the driving evaluation application 82A is executed by the processor, the data acquisition unit 32A, the gradient acquisition unit 34A, the image analysis unit 36A, the object recognition unit 38A, the lane recognition unit 40A, and the information processing unit 42A are realized.

  The terminal device 50A is fixed to, for example, a pedestal provided on the upper surface of the instrument panel of the host vehicle M. Specifically, in the state in which the driving evaluation application 82A is executed, the terminal device 50A has a position where the acceleration sensor 14A can appropriately detect the acceleration with respect to the host vehicle M, and a position where the camera 12A can capture the front of the vehicle. It is attached. Then, the terminal device 50A executes notification processing and evaluation processing based on the acceleration detected by the acceleration sensor 14A and the image captured by the camera 12A.

  According to the embodiment described above, the acquisition unit 62 that acquires the acceleration of the host vehicle M and the operation state of the direction indicator 20 and the acceleration of the host vehicle M to the user when the acceleration is equal to or greater than the first predetermined value. When the control unit 64 causes the output unit to output a notification that prompts suppression, the acceleration is equal to or higher than a first predetermined value, and information that can recognize that the direction indicator 20 is operated is acquired. By providing the control unit 64 that does not perform notification, it is possible to perform notification in accordance with the actual traffic situation.
